Improvement in sieves



UNITED STATES GEORGE WRIGHT, OF SAVANNAH, MISSOURI.

IMPROVEMENT lN SIEVES.

Specification forming part of Letters Patent No. 138,976, dated May 13, 1873; application filed January 11, 187 3. i

To all lwhom it may concern:

Be it known that I, GEORGE WRIGHT, of Savannah,in the county of Andrew and State of Missouri, have invented a new and valuable Improvement in Sieves; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specication and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of my wire-cloth. Fig. 2 is a sectional view of my sieve. Fig. 3 is an enlarged detail, showing groove.

This invention has relation to the construction of sieves having metallic rims; and it consists in the manner of fastening the wirecloth to the rim by soldering the free edge of the wire-cloth within a groove' swaged in the` In the accompanying drawing, the letter A lndicates the metallic rim, in which is swaged a groove, b, parallel with its bottom edge. O designates the wire-cloth, cut sufficiently large for its edge to extend within the groove b. The wire-cloth is then fastened in the groove by the application of solder d, which fills the groove and at the same time forms a stout metallic edge to the wire-cloth.

An examination of this fastening will show that it is very secure. The groove affords a rm hold to the solder, and this in turn is so intimately looped in and connected with the meshes at the edge of the wire-cloth that it is impossible to separate the two by ordinary use.

What I claim as my invention, and desire to secure by Letters Patent, is-

The sieve A, constructed with groove b to receive the sieve-bottom, the free ends of the wire being secured together and to the vessel by solder, as described and shown.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE WRIGHT.
